<h2>Why is this an issue?</h2>
<p>A function that grows too large tends to aggregate too many responsibilities.</p>
<p>Such functions inevitably become harder to understand and therefore harder to maintain.</p>
<p>Above a specific threshold, it is strongly advised to refactor into smaller functions which focus on well-defined tasks.</p>
<p>Those smaller functions will not only be easier to understand, but also probably easier to test.</p>
